Section 2 — Key sector accounting differences (IFRS 9 vs ASC 326)
[T1] See ifrs-local-gaap-reconciliation.md for the underlying difference catalogue.
For banking specifically:
| Item | IFRS 9 | ASC 326 (CECL) |
|---|---|---|
| Loss model | 3-stage Expected Credit Loss | Current Expected Credit Loss — lifetime ECL from inception |
| Day-1 allowance | 12-month ECL only | Lifetime ECL (typically higher) |
| Significant increase in credit risk (SICR) | Threshold (typically 30-day past due rebuttable presumption + qualitative) | n/a in CECL but used for monitoring |
| Originated credit-impaired (POCI) | Effective interest rate based on lifetime expected cash flows; subsequent ECL changes through P&L | ASU 2022-02 conformed POCI treatment |
| Off-balance-sheet (loan commitments, financial guarantees) | Stage-based ECL | CECL |
Section 3 — Tax treatment of loan loss provisions
[T1] By jurisdiction (sample):
| Country | Treatment |
|---|---|
| US | Loan loss reserve deductible only for small banks (assets ≤ USD 500m) under §585; non-thrift banks use specific charge-off method (§166). ASC 326 CECL accounting does not flow through 1:1 to tax. |
| UK | General provisions not deductible; specific provisions deductible if linked to identifiable loss event and meets HMRC commercial test. IFRS 9 Stage 3 generally deductible; Stages 1/2 generally not |
| Germany | Allgemeine Risikovorsorge limited; spezifische Wertberichtigungen deductible when "objectively required" — pre-tax overlay |
| France | Provisions pour dépréciation generally deductible if probable and quantifiable |
| Italy | Banking sector loan loss provisions deductible on schedule (18% of book in year 1 historically; now reformed to align IRES treatment) |
| Australia | Specific loss provisions deductible; general not |
| Canada | Specific allowance deductible; general allowance non-deductible |
| India | Specific provisions allowed only to extent prescribed by RBI; bad-debt write-offs deductible |
[T1] Material book-tax difference creates substantial deferred tax assets (DTAs) for banks. Recoverability assessment under IAS 12 / ASC 740 critical — Pillar Two interacts as DTAs may recapture under the 5-year rule.
Section 4 — Bank levies and surcharges
4.1 UK Bank Levy + Bank Surcharge
[T1] UK Bank Levy (Finance Act 2011 Schedule 19):
- Rate: 0.10% of taxable balance sheet equity and liabilities (reduced to 0.10% from 0.21% in stages, FA 2017)
- Half rate (0.05%) on long-term funding
- De minimis: GBP 20bn balance sheet
- Filing: HMRC bank levy return, due 9 months 1 day after period end
[T1] UK Bank Corporation Tax Surcharge (FA 2015 s.17 amended FA 2022):
- Rate: 3% on bank profits above GBP 100m (reduced from 8% effective 1 April 2023)
- Applies in addition to standard 25% CT
- Effective rate on banking profits above threshold: 28%
4.2 EU Single Resolution Fund (SRF) contribution
[T1] Ex-ante annual contributions under Regulation (EU) 806/2014 to fund bank resolution; calculated by the Single Resolution Board based on liabilities. Target level: 1% of covered deposits at SRF maturity (2024). Distinct from country deposit guarantee scheme (DGS) contributions.
4.3 EU Member State bank levies
| Country | Rate | Base |
|---|---|---|
| Germany | EUR 410-1.6bn annually distributed across banks | Risk-weighted liabilities — Bankenabgabe |
| France | Contribution sur les établissements de crédit reformed; merged into SRF + national supplement | Risk-weighted exposures |
| Italy | Imposta straordinaria 2023 (40% on certain net interest gains) — converted to optional reserve contribution following ECB pushback | Net interest income excess |
| Spain | 4.8% on net interest + commissions (extraordinary 2023-2025; targeted "windfall" tax) | Spanish-source banking gross income > EUR 800m threshold |
| Hungary | Bank levy — 0.15% / 0.20% balance sheet thresholds | Liabilities |
| Sweden | Bank tax — 6% on liabilities; reduced 2024 | Total liabilities |
| Belgium | Bank levy on liabilities | Liabilities |
| Netherlands | Bankenbelasting — 0.044% short-term / 0.022% long-term liabilities | Liabilities |
| Poland | Bank levy 0.0366% per month (0.44% annually) | Excess assets above PLN 4bn threshold |
4.4 Deposit Guarantee Scheme (DGS) contributions
[T1] EU Directive 2014/49/EU. Country DGS funds ex-ante and ex-post contributions from member banks.
Section 5 — DTAs and Pillar Two interaction
[T1] Banks typically hold material DTAs from:
- IFRS 9 ECL (book in advance of tax)
- Pension obligations (book provisions in advance of tax)
- Deferred compensation
- Operating loss carryforwards
- Securitisation losses
[T1] Basel III prudential filter under Article 36(1)(c) CRR:
- DTAs that rely on future profitability must be deducted from CET1 above a 10% threshold (combined with other deductions)
- DTAs from temporary differences taxed at deferred 15%+ generally less restrictive
[T2] Pillar Two interaction:
- DTAs / DTLs revalued to lower of statutory rate or 15% (per
pillar-two-globe-minimum-tax.md) - 5-year DTL recapture rule may add back loan loss DTL recoveries
- ETR may fall below 15% for banks with material loss carryforwards in low-rate jurisdictions
Section 6 — Sector-specific issues
6.1 Trading book vs banking book
[T1] Trading book positions:
- IFRS 9: typically FVPL (held for trading)
- Tax: most jurisdictions tax mark-to-market gains on banking trading books (UK FA 2002 Sch 26; US §475 mark-to-market election for dealers)
Banking book positions:
- IFRS 9: amortised cost or FVOCI
- Tax: realised basis typically
6.2 Hedge accounting and tax
[T1] IFRS 9 / ASC 815 hedge accounting reduces P&L volatility but creates timing differences for tax:
- Cash flow hedges: deferred in OCI, recycled to P&L on hedged item recognition — tax follows P&L timing
- Fair value hedges: P&L immediate offset — tax generally follows
6.3 Securitisation
[T1] Tax treatment depends on consolidation and risk transfer:
- True sale + non-consolidated SPV: gain/loss on sale, no further bank tax on SPV income
- Synthetic / retained risk: continued bank tax on underlying loans
- IFRS 10 / ASC 810 may differ from regulatory consolidation
- §163(j) US interest deduction limitation interactions
6.4 Interchange and merchant services
Card interchange revenue is service revenue subject to standard CIT. Merchant discount rate (MDR) flows to processor / bank. Specific country VAT exemptions for "financial services" generally cover interchange.
6.5 Credit valuation adjustment (CVA)
Tax treatment varies — some jurisdictions allow deduction of CVA P&L volatility; others require add-back of fair value losses on counterparty risk.
